2024-2025 Audi e-tron GT Electrical System Fault TSB

Owners of 2024-2025 Audi e-tron GT and RS e-tron GT vehicles may encounter an "Electrical system: fault" warning message. This Technical Service Bulletin (TSB) 2080127/1, released on November 24, 2025, details the symptoms and the necessary software update to resolve this condition.

Symptoms

When the ignition is switched on, a yellow warning lamp may illuminate in the instrument cluster. This is accompanied by the message: "Electrical system: fault. Please contact workshop". When this warning appears, the vehicle cannot be driven. However, cycling the ignition off and then back on typically clears the message, allowing the vehicle to be driven without further restrictions.

Diagnosis and Trigger Conditions

Audi has identified that certain customer usage behaviors can lead to a temporary restriction in the function of a specific system within the vehicle. This temporary restriction is what triggers the "Electrical system: fault" warning. The issue is not a permanent hardware failure but rather a software-related anomaly.

The Solution: Software Update

The primary solution for the Audi e-tron GT electrical system fault is a comprehensive software update. This update has been specifically prepared to repair the underlying issue and includes updates for various control units within the vehicle. Audi is publishing this as a combined software update to ensure all affected systems are properly synchronized.

This TSB 2080127/1 replaces the previous Pending Service Solution (PSS) TSB 2075720, which also addressed the "93 Warning message: "Electrical system: fault. Please contact workshop" (e-tron GT)" condition. For new vehicles, this updated software will be integrated into series production starting in Q3/2025.

Further details regarding this combined software update can be found in related bulletins: TSB 2079980, which covers the "91 MMI software update, connectivity box for MIB3 vehicles (version MLB e-tron GT ST3BP with AED)", and TSB 2079979, for the "91 MMI software update, connectivity box for MIB3 vehicles (version MLB e-tron GT ST3BP without AED)". These bulletins provide additional context for the broader software improvements included in this update.

Important Warnings and What Owners Should Know

It is critical to understand that when the "Electrical system: fault. Please contact workshop" message is active, the vehicle cannot be driven in this condition. While switching the ignition off and on may temporarily clear the message and allow the vehicle to operate, this does not resolve the underlying issue. Owners should arrange for their vehicle to be serviced promptly to receive the necessary software update.

All information, parts, and service references provided in TSB 2080127/1 are subject to change or removal. Owners should always consult with their Audi Parts Department or ETKA for the latest information and bulletins.
